Configuring Availability for Individual Web Applications

To enable and configure availability for an individual web or converged web or SIP application, edit the application deployment descriptor file, sun-web.xml. The settings in an application’s deployment descriptor override the web container’s availability settings.

The session-manager element’s persistence-type attribute determines the type of session persistence an application uses. It must be set to replicated to enable high availability session persistence.

For more information about the sun-web.xml file, see The sun-web.xml File in Sun GlassFish Communications Server 2.0 Application Deployment Guide.

Example

<sun-web-app> ... 
  <session-config> 
    <session-manager persistence-type="replicated"> 
      <manager-properties> 
        <property name="persistenceFrequency" value="web-method" /> 
      </manager-properties> 
      <store-properties> 
        <property name="persistenceScope" value="session" /> 
      </store-properties> 
    </session-manager> ... 
</session-config> ...
